Abstract

A system for non-destructive underwater evaluation of structures comprises an ultrasonic testing means, such as a transducer, means for converting the output thereof into a visual signal, such as an oscilloscope, and means for conveying that visual signal to the underwater technician who is operating the ultrasonic testing means. The means for transmitting the visual signal may comprise an underwater television or other monitor, connected either to a television camera which photographs the output of the oscilloscope or other visual display device, or other means, such as an auxiliary cathode ray tube display device, can be hooked directly to the visual display device. Preferably recording means, such as a video tape recorder, is connected, together with the underwater monitor, to make a permanent record of the monitored signals. Most preferably, the underwater monitor is also attached or attachable to an underwater television camera, so that the inspection can be switched from visual to ultrasonic, or vice versa, at will. Preferably the system also permits direct visual communication between the underwater technician and the topside crew. [US4102203A]
